Minneapolis, MinnesotaAges Any age - NCT06081517Recruiting
Study of fairness in genetic cancer testing
This study looks at how well precision medicine (treatments based on your tumor's genes) is used for people with cancer. Researchers want to see if there are differences in who gets this kind of testing and treatment, so they can make it more fair for everyone.
Indianapolis, IndianaAges 18 years+ - NCT06083155Enrolling by invitation
Dutch registry of coronary function tests
This study collects information from people who are already scheduled for a coronary function test, to learn more about heart vessel health. By joining, you help researchers understand patterns and improve care for others.
